The “Anger Management” star broke the news Thursday when she posted a photo of herself, in costume on set, accompanied by the caption, “Do I look like step Mother Theresa?” (a nod to a line from the 1988 cult film).

Blair will recur as Jade, a rough-edged, gold-digging stripper who is married to the 82-year-old father of Heather Duke (played by Brendan Scannell).

Described by the network as a “pitch-black comedy anthology set in the present day,” “Heathers” follows Veronica Sawyer (played by “Under the Dome'” Grace Victoria Cox) and a trio of vicious Heathers played by relative newcomers Melanie Field, Scannell and Jasmine Matthews. James Scully will play JD.

As previously announced, original film cast member Shannen Doherty (“Charmed;” “Beverly Hills, 90210”) will guest-star as a “pivotal, unnamed” role in the reboot, which was originally planned for TV Land but now is slated to debut in 2018 on Paramount Network (which is what the cable channel now known as Spike TV will be called, come January).
